Optimization Of Cutting Parameters

A finite element simulation study of cutting process and whole part deformation of a large thin-wall aluminum alloy part used in aerospace is carried out by ABAQUS. The geometry model, material model and heat conduction model are built. The friction conditions and boundary constraints are determined. The whole process of chip generation is simulated and the distribution of strain, stress, cutting temperature and are given. The chip formation and the cutting force are also predicted. Based on the prediction results, the deformation of whole part is predicted. This study establishes the foundation of selection and optimization of cutting parameters and deformation compensation for this kind of large thin-wall parts.

Row Of Fibers

The morphology and composition of the fiber-matrix interface can best be studied by transmission electron microscopy and electron diffraction. For some composites satisfactory samples can be prepared by electropolishing. For others such as aluminum alloy-boron composites ion erosion is necessary.When one wishes to examine a specimen with the electron beam perpendicular to the fiber, preparation is as follows: A 1/8 in. disk is cut from the sample with a cylindrical tool by spark machining. Thin slices, 5 mils thick, containing one row of fibers, are then, spark-machined from the disk. After spark machining, the slice is carefully polished with diamond paste until the row of fibers is exposed on each side, as shown in Figure 1.In the case where examination is desired with the electron beam parallel to the fiber, preparation is as follows: Experimental composites are usually 50 mils or less in thickness so an auxiliary holder is necessary during ion milling and for easy transfer to the electron microscope. This holder is pure aluminum sheet, 3 mils thick.
